One way we would have known that we had hit peak oil with increasing demand, is that the price would go up.

However, due the intransigent (inelastic) demand of motorists, OPEC has managed to increase the price of oil from $20 to $70 a barrel. This would have happened anyway since there is little spare capacity.

This has at least held demand steady in the US, although gas guzzler sales are on the rise again.

So we have the effects of an oil peak, without there being a peak, and should adapt accordingly.

The best way to hold down CO2 increases is to remove fossil fuels from electricity generation, but use it just for vehicles.

Since ½ of US electricity comes from coal which generates twice as much CO2 per energy unit as does natural gas, we should switch to natural gas. This, however, involves massive and possibly costly imports.

We need increases in alternate energy sources such as hydro, nuclear, wind and solar.
